I think we have two questions here. One involves the tow "rating" of the truck and the other is the "capacity" of some of it's "components". While components can be changed that are stronger, etc. than original, it is my understanding that the tow "rating" of a particular truck can not be changed. It is what was the day it left the factory and no changing of parts will change that original rating.
That is not entirely true.
There ARE shops out there which are "licensed upfitters". They have the engineering staff (often one engineer) to certify changes to
ANY rating on a truck. They can and will install suspension parts, gearing, etc. to allow heavier loads to be carried or towed. They can replace the factory ratings sticker with a new one.
Of course, the GCWR and/or towing rating are seldom on the sticker anyway. On all the trucks I have owned, it is a rating that only appears in the Owners Manual.
It seems to be a "numbers game" that the manufacturers use so their marketing departments can say "WE are the best!"
